976,434. 'A Specification of Letters Patent.

Application filed January 3, 1910. Serial No. 536.667.

To all 'whom it muy concern.' ,e

Be it known that l, Anoxman JL Corman, a citizen4 of the United States, residing at Yreka, in the county ot' Siskiyou and State of California, have invented new and useful Improvements in Ditch-Gates, ot' which the.

following is a specification.

This invention relates to ditch gates.

It is the purpose ot' my invention to provide a gate adaptable equally to control the ,flow of water through canals tunnels,

ditches',` lumcs, etc.; to lprovide a gate of peculiar structure and design, and to provide a packing in combination with. the gate ot' exceptional etliciency and strength.

The invention consists of tlielpar't's, and

the construction. and combination of parts as hereinafter more fully described and claimed, havingireference to the accompanying drawings, in which Figure 1 isa vertical, longitudinal section of the gate as applied to a tunnel. F i. Y. QIis a plan of same. Fig 3 is a rear eleatron of the curtainpacking. .Fig 4 is a transverse, sectional detail of a packing bar .Fig 5 shows a modified form of curtain packing.

The embodiment of my invention us illusti'iited, comprises a gate A of any suitable material, so designed and const tiufted as to have its face concentric with a pivot or in verted U-shaped bearing 2 upon which the gate may swing to'control the flow of water `iti-om the, head B to a branch canal or ditch C.

W'hen the gate is applied to a tunnel, as B, its height arid width are such as to conform closely. to the relative. dimensions Vot" the tuinnel g and to prevent leakage of water around the edges of the gate T providepaeking bars or members 3 of appropriate material :ir-

i'ar'iged contiguous to the `vertical and the .witoni edges ot' the gate.

and to protect the packing strip from :ibi-asion and injury it is covered by a thin sheet s of metal or other .sufficient substitute obtained, and therefore the bars are preterably Secured to the frate by suitable. bolts, or

the equivalent, (l, either having play in the l' prefer to ecn- 'structthese packing bars ot' trianeular material and place them in such position thaty thchypotenuse is presented to the'pressure 5 of water, and is covered with a. strip ot p'acking material -l adapted to lap upon the sur-fz face. of the gate and of the tunnel or ditch, 'i

gate or in the bars, or both, to permit the against the ivalls of the tunnel.

. '.to prevent leakage at the upper edge of the gate, there is employed a movable curtaiirlike member 7, attached in a convenient manner, as by pivot pins or bolts 8 to the thrust into snug contact against the upper portions of the door.

The member 7 is cut angularly` on its ends (Fig. 2), to allow the angular' packing bars 3, secured to gate A, to passiipwardlv without interference, and to the curtain. member is suitably fastened a strip of liexible packing material 9 closely following the exposed edges of the curtain and ada ted to bear upon theV gate and tunnel sur aces, a sheet of packing 10 being also secured to theupper plane of the curtain 7 preventing leakage above tlie gate. i A. It will thus be seen that the gateis thorpu'ghly provided at all points Where leakage is likely to occur, with a. packin device that is reliablersimple and perfect y protected, and for the purpose of reducing the resistance ot' the gate during adjustment, it is provided adjacent t0 its Vertical edges, with antitriciion rollers 11 adapted to bear upon the walls of the canal.

Under certain comlitions it is advantageous to employ a curtain packing such as shovvn in Fig. 5, comprising a triangular bar 12, loosely.' mounted on bolts 1B secured in the tunnel root', and having one concave face i hearing upon the gate A. Upon the wide side of the bar is laid a packing Strip 14 covered and protected by a. suitable facing 15 fastened to the bar.

When subjected to pressure the various 5 packing members are Jforced into Water-tight contact with thegate and wallshand )et do not bind the gate or interfere with its adjustment; and further the rollers 11 always maintain the gate equiilistant. between the walls. thus preventing the gato .shift-ing sideivise tightly against either wall.

llaviug thus descril'ieil my invention, what .l claim and vdesire to secure by Letters Patent is 1.4 The combination with a Water system, of a pivoted adjustable gate, packing inein-A bers mounted thereon contiguous to its edges, and a packin` curtain mounted indel lunilently ot but a apted to bear upon the l gate.
